0前言 根据原国家机械工业委员会1988年机械工业科学技术发展计划（工程农机标准制、修订部分）的规定,编号为88410207的国家标准GB1149—82《内燃机活塞环技术条件》于88年到89年进行修订。1988年3月由石家庄内燃机配件总厂、上海内燃机配件总厂、仪征活塞环厂、安庆活塞环厂和上海内燃机研究所组成修订工作组,同时讨论了上海内燃机研究所所提出的修订大纲。88年5月根据修订大纲,由上内所起草修订稿,并在88年10月于仪征举行工作组会议（聊城活塞环厂参加了讨论）,形成讨论稿。88年12月发有关活塞环厂和主机厂征求意见。89年2月于无锡再次举行工作组会议（无锡活塞环厂参加了会议）,经过讨论认为各单位意见比较一致,故于89年5月将函审稿发往有关单位函审。到89年7月底收到的函审意见也都表示同意或修改后同意。我们已将意见汇总处理后,以报批稿上报部局审批。为了便于各单位了解情况,特将修订情况作如下介绍。
0 Foreword According to the original National Machinery Industry Committee’s 1988 Machinery Industry Science and Technology Development Plan (Project Agricultural Machinery Standards, Revision), the national standard GB1149-82 “Technical conditions of piston rings for internal combustion engines” No. 88410207 was made between 88 and 89 years. Make amendments. In March 1988, a revised working group was formed by Shijiazhuang Internal Combustion Engine Fittings Plant, Shanghai Internal Combustion Engine Fittings Plant, Yizheng Piston Ring Plant, Anqing Piston Ring Plant, and Shanghai Internal Combustion Engine Research Institute. At the same time, the revised outline proposed by Shanghai Institute of Internal Combustion Engines was also discussed. In May 88, according to the revised outline, the revised draft was drafted by Shangchi and a working group meeting was held in Yizheng in October, 88 (the Liaocheng Piston Ring Plant participated in the discussion) to form a discussion draft. In December of the year, it issued opinions about the piston ring factory and the main engine plant. In February of the same year, a working group meeting was held in Wuxi (Wuxi Piston Ring Factory participated in the meeting). After discussion, the opinions of all units were relatively consistent. Therefore, in May of the same year, the review draft was sent to the relevant unit for correspondence. The letter of advice received by the end of July of the same year also indicated that they agreed or revised the agreement. After we have consolidated the opinions, we submit the drafts to the Ministry for approval. In order to facilitate the understanding of the situation of various units, the amendments are described as follows.
